Description

BACKGROUND

Work machines, such as those used in the agriculture, construction, forestry industries and elsewhere, may be utilized for lifting, moving, and/or otherwise handling materials. In one non-limiting example, a backhoe may include a bucket pivotally coupled by a boom arm to the vehicle chassis. One or more hydraulic cylinders may move the boom arm and/or the bucket relative to the vehicle chassis to perform intended operations. Further, a work vehicle may be required to traverse a work area or other area for intended operations. Designing the structural assemblies of work machines, such as the boom arm of a construction vehicle in the non-limiting example, involves various considerations including, for example, strength, durability, wear resistance, and the amount and type of material the structure is capable of lifting, moving, or otherwise handling. While strength of such structures for work machines may be a focus to handle the substantial volume and weight of the material being moved and handled, substantial energy is required to move and operate such structural assemblies due to the associated weight and inertia. Further, machining, welding, forming, and/or assembling the work machine structures requires extensive tooling, equipment, expense, and energy.

In the particular embodiment of FIG. 3, two or more second node cavities 30 for each node member 16 are shown. In embodiments not illustrated, one or more of the nodes 16 do not include the second node portion 28. In the illustrated embodiments, the first node portion 24 and the second node portion 28 are configured to engage each other. The first node portion 24 and the second node portion 28 are configured to respectively form or occupy a first side 32 of the node member 16 and a second side 34 of the node member 16 that is opposite the first side 32. In particular embodiments herein, the first node portion 24 and the first node cavity 26 may be referred to as a primary node portion with a primary node cavity, respectfully, and the second node portion 28 and the second node cavity 30 may be referred to as a secondary node portion with a secondary node cavity, respectfully. As illustrated in FIG. 3, the first node portion 24 joins, engages, couples or connects to, interfaces, assembles with, or otherwise meets the second node portion 28 generally along a joining plane 36. In the resulting assembly, the joining plane 36, in at least the embodiment illustrated in FIG. 3, is generally parallel to the longitudinal axis 18 of one or more of the struts 14 in the assembly 12. In an embodiment, the

node portions

24, 28 interlock to form the node member 16. Although the present embodiments illustrate U-shaped

node cavities

26, 30, in additional embodiments not illustrated, one or more of the node members 16 includes a cross-section that is L-shaped, resulting in complementary L-shaped

cross-sectional node cavities

26, 30, or another cross-section to result in the

node cavities

26, 30.

In the illustrated embodiment of FIG. 3, the first end portion 20 of one of the struts 14 is configured to engage the first node portion 24 of a first one 38 of the node members 16. The second end portion 22 of the strut 14 is configured to engage the first node portion 24 of a second one 40 of the node members 16. As illustrated in FIG. 3, the node members 16 of an embodiment include one or more terminating node members 42 and one or more joining node members 44. In an additional embodiment not shown, the assembly 12 does not include joining node members 44.

FIG. 5 illustrates a further embodiment of the assembly 12 of the present disclosure. The various embodiments of the assembly 12 contemplated by the present disclosure include any number of struts 14 and any number of nodes 16. As non-limiting examples, FIGS. 2-4 illustrate the assembly 12 having three nodes 16 and four struts 14, while the embodiment of FIG. 5 illustrates an assembly 12 having four nodes 16 and fourteen struts 14. The assembly 12 of FIG. 5 includes two joining node members 44 and two terminating node members 42. One of ordinary skill in the art, upon review and understanding of the present disclosure, will recognize the various node and strut amounts, orientations, positions, and configurations that are possible to form the assembly 12, and all such configurations are included as additional embodiments in the present disclosure.

In the embodiments illustrated in FIGS. 2 and 3, one or more of the terminating node members 42 includes at least one hole or bore 80 configured to form an end portion 82 of a boom of the work machine 10. In an additional embodiment, one or more joining node members 44 includes one or more holes or bores 80. The bore 80 may be utilized for attachment and/or operation of a work tool, actuator, or other structure, such as a bucket, secondary boom, or hydraulic cylinder to name non-limiting examples.

To further describe the interconnected structure of the assembly 12, in the illustrated embodiment shown in FIG. 3, each of the node members 16 includes the first node portion 24 having, for each strut 14 connected thereto, the first node cavity 26 and the second node portion 28 having, for each strut 14 connected thereto, the second node cavity 30. FIG. 4 illustrates two struts 14 and the first node portion 24 of one embodiment. Referring to FIG. 3, the first end portion 20 of a first strut 48 is configured to engage the first node portion 24 and the second node portion 28 of a first node member 50, and the second end portion 22 of the first strut 48 is configured to engage the first node portion 24 and the second node portion 28 of a second node member 52. Further, the first end portion 20 of a second strut 54 is configured to engage the first node portion 24 and the second node portion 28 of the first node member 50, and the second end portion 22 of the second strut 54 is configured to engage the first node portion 24 and the second node portion 28 of the second node member 52. However, in additional embodiments such as that illustrated in FIG. 5, the first strut 48 and the second strut 54 connect the first node member 50, the second node member 52, and a third node member 56. Such arrangements may be utilized and repeated to form additional portions of the assembly 12, and, as stated above, the various node and strut amounts, orientations, positions, and configurations of the assembly 12 are included as additional embodiments in the present disclosure.

As illustrated in FIGS. 2 and 3, the longitudinal axes 18 of the first strut 48 and the second strut 54 are configured to form a generally V-shaped assembly 60 of the first strut 48 and the second strut 54. The longitudinal axes 18 of the first strut 48 and the second strut 54 are further configured to form a first separation 64 at a first end 66 and a second separation 68 at a second end 70. The first separation 64 is greater than the second separation 68. Further, the longitudinal axes 18 of the first strut 48 and a third strut 58 are configured to form a generally V-shaped assembly 62 of the first strut 48 and the third strut 58. The longitudinal axes 18 of the first strut 48 and the third strut 58 are further configured to form a first separation 72 at a first end 74 and a second separation 76 at a second end 78. The first separation 72 is greater than the second separation 76. In one or more embodiments, such as the embodiment illustrated in FIG. 5, the longitudinal axes 18 of one or more struts 14 are substantially parallel to each other.

In one embodiment, one or more of the joining node members 44 connects two struts 14 to form an angle θ between the struts 14 of between 90 degrees and 180 degrees. One or more of the joining node members 44 connects two struts 14 to form an angle θ between the struts 14 of between 110 degrees and 170 degrees, in an additional embodiment, and an angle θ between the struts 14 of between 130 degrees and 160 degrees in an additional embodiment.

As shown in FIGS. 3 and 4, one or more of the node members 16, such as the joining node member(s) 44 and/or the terminating node member(s) 42, have a hollow central body 114 in the illustrated embodiment. In the illustrated embodiment of FIG. 3, one or more fasteners 102 secure, couple, or otherwise join the first node portion 24 to the second node portion 28. The fastener(s) 102 of the embodiment of FIG. 3 are spaced from the first node cavity 26 and the second node cavity 30 and do not extend through or contact the first node cavity 26 or the second node cavity 30. In additional embodiments not illustrated, one or more of the fastener(s) 102 are not spaced from the first node cavity 26 and/or the second node cavity 30 and may extend through or contact the first node cavity 26 and/or the second node cavity 30 for further coupling or reinforcement. In further embodiments not shown, other fastening structures or methods, welding, interference fitting, integral formation, and/or other joining methods may be utilized to form the assembly 12 described herein.

Referring again to the embodiment illustrated in FIGS. 2-4, an adhesive 46, such as in the form of an adhesive layer or coating, is utilized in the assembly 12 and is configured to bond the first end portion 20 and the second end portion 22 of the strut 14 to node members 16 at the first node cavity 26 and the second node cavity 30. The adhesive 46 may be acrylic, urethane, epoxy, or mixtures thereof, in one or more embodiments. In one non-limiting embodiment, the adhesive 46 has a shear strength between 20 MPa and 8 MPa with elongation at break above 40% at 23° C. In particular embodiments of the present disclosure, the adhesive 46 may cure at room temperature under ambient conditions or may be cured through other mechanisms, such as by heating. One non-limiting example of the adhesive 46 is the commercially available adhesive Plexus MA425, available from ITW Performance Polymers of Danvers, Mass.

With reference to FIG. 4, the

end portions

20, 22 of each strut 14 include an outer surface 84. The outer surface 84 in the illustrated embodiments extends in a direction generally parallel to the longitudinal axis 18 of the strut 14. The first node portion 24 and the second node portion 28 of the node member 16 are configured to join around one of the

end portions

20, 22 of each strut 14. In the illustrated embodiment, the first node cavity 26 and the second node cavity 30 of the node member 16 are configured to join around one of the

end portions

20, 22 of each strut 14. The adhesive 46 is disposed between the outer surface 84 and the first node cavity 26 and, in at least one embodiment, the second node cavity 30. The adhesive 46 may be applied initially to one or both of the

node cavities

26, 30 and/or any portion of the outer surface 84 of the strut 14.

Referring now to the partial cross-sectional views of FIGS. 6a and 6b , and with continuing reference to FIG. 4, one or both of the

end portions

20, 22 includes an end portion first side 86 and an end portion second side 88. One or both of the end portion first side 86 and the end portion second side 88 has opposing

surfaces

90, 92 extending along

non-parallel planes

94, 96 in the embodiment shown in FIG. 6a . In additional embodiments not illustrated, one or both of the end portion first side 86 and the end portion second side 88 may have opposing

surfaces

90, 92 extending along parallel planes or substantially parallel planes. The outer surface 84 of one or both of the end portion first side 86 and the end portion second side 88 further includes an intermediate portion 98 disposed between the opposing

surfaces

90, 92 that is at least partially flat. In additional embodiments not illustrated, the intermediate portion 98 is rounded or otherwise non-flat. As FIG. 6a illustrates, at least the first node cavity 26 includes cavity surfaces 100 that are generally complimentary, or respectfully parallel, corresponding, or otherwise geometrically equal, to the opposing

surfaces

90, 92 of the end portion first side 86. Similarly, although not illustrated in FIG. 6a , the second node cavity 30 includes the cavity surfaces (not shown) that are generally complimentary, or respectfully parallel, corresponding, or otherwise geometrically equal, to the opposing surfaces (not shown) of the end portion second side 88.

FIG. 6b illustrates the strut 14 in a joined position with one of the

node cavities

26, 30. The complimentary arrangement of the outer surface 84 of the strut 14 and the first and

second node cavities

26, 30 permits consistent or substantially equal spacing between the outer surface 84 of the strut 14 and the first and

second node cavities

26, 30 and, in at least one embodiment, a consistent or substantially equal thickness layer of adhesive 46 between the outer surface 84 of the strut 14 and the first and

second node cavities

26, 30. Such an arrangement allows all portions of the outer surface 84 to simultaneously contact all portions of one of the first and

second node cavities

26, 30, thereby reducing or preventing wiping or other undesirable movement or disturbance of the adhesive 46 from the surface of the strut 14 and/or the first and

second node cavities

26, 30. With the adhesive 46 maintained as a consistent layer or otherwise remaining generally undisturbed through joining, the intended design strength and other intended properties and characteristics of the assembly 12 remains substantially unaffected, the quality of the assembly 12 is maintained, and/or the properties and behavior of the assembly 12 are predictable and consistent.

To further reduce or prevent wiping or other undesirable disturbance of the adhesive 46, the assembly 12 of an embodiment further includes one or more guiding members 104, such as a dowel rod to name a non-limiting example, disposed in one or both of the first node portion 24 and the second node portion 28, as referenced in FIG. 4. The guiding member(s) 104 are configured to guide the joining of the first node portion 24 to the second node portion 28. Specifically, one or both of the first node portion 24 and the second node portion 28 include guide holes 106 configured to receive the guiding member(s) 104 such that one or both of the first node portion 24 and the second node portion 28 follows a predetermined path for joining. The predetermined path in the illustrated embodiment is generally perpendicular to the longitudinal axis 18. Accordingly, the guiding member(s) 104 are configured to permit portions of one of the first and

second node cavities

26, 30 to simultaneously contact the portions of the other of the first and

second node cavities

26, 30 and the outer surface 84 of the strut 14, thereby reducing or preventing wiping or other undesirable movement or disturbance of the adhesive 46 from the surface of the strut 14 and/or the first and

second node cavities

26, 30. The guiding members 104 of the illustrated embodiment remain with the assembly 14 following formation. In additional embodiments, the guiding members 104 are removed following formation of the assembly 12, such as part of a fixture or assembly jig.

Referring again to FIG. 4, one or both of the first node portion 24 and the second node portion 28 includes one or more joining surface(s) 108 spaced from the first node cavity 26 and the second node cavity 30. The joining surface(s) 108 has disposed thereon, in an embodiment, a layer or other arrangement of adhesive 46 that is contiguous with the adhesive 46 used to adhere the strut 14 to one or both of the first node portion 24 and the second node portion 28. In another embodiment, the adhesive 46 disposed on the joining surface 108 is not contiguous with the adhesive 46 used to adhere the strut 14 to one or both of the first node portion 24 and the second node portion 28. Further, one, some, or all of the joining surfaces 108 extends in a direction of assembly that is not parallel to the direction of assembly in order to avoid wiping or other disturbance of the adhesive 46 disposed thereon, similar to the surfaces of the

cavities

26, 30, as described above. The joining surfaces 108 of an embodiment are configured to provide maximum adhesive surface area, such as by providing surface area along multiple planes in one non-limiting exemplary embodiment, thereby increasing strength of the joint between the first node portion 24 and the second node portion 28.

Further shown in FIGS. 3 and 4, one or more of the nodes 16 includes one or more tapered interface portion(s) 110 as part of an outer surface 112 of the node 16 at the interface between the strut 14 and the outer surface 112 of the node 16. The tapered interface portion 110 is characterized by a reducing thickness such that a thickness of the interface portion 110 proximal to the strut 14 is less than a thickness distal to the strut 14. The tapered interface portion(s) 110 prevents or reduces stress concentration at such locations of the node 16 near the strut 14.

Referring now to FIG. 8, a method 200 of assembling the node and strut structural assembly 12 is provided. The method 200 includes applying, at step 210, the adhesive 46 to the first node cavity 26 of the first node portion 24 and the second node cavity 30 of the second node portion 28. The method 200 further includes positioning, at step 212, one of the

longitudinal end portions

20, 22 of the strut 14 in the first node cavity 26 of the first node portion 24. The method 200 further includes joining, at step 214, the second node portion 28 to the first node portion 24 such that the

longitudinal end portion

20, 22 of the strut 14 is positioned in the second node cavity 30.

The method 200 of additional embodiments further includes guiding one or both of the first node portion 24 and the second node portion 28 toward joining with the other with the guiding member(s) 104 and joining the first node portion 24 to the second node portion 28. The method 200 of additional embodiments further includes fastening, welding, or otherwise joining the first node portion 24 and the second node portion 28 together, such as with fasteners or another secondary joining method or structure. The method 200 of additional embodiments further includes applying the adhesive 46 to the first node cavity 26 and the second node cavity 30 and, in additional embodiments, applying the adhesive 46 to the joining surface(s) 108 and/or another surface of the central body 114 of the node member 16. The method 200 may further include roughing one or more surfaces of the

node cavities

26, 30 before applying the adhesive 46 to the first node cavity 26 of the first node portion 24 and/or the second node cavity 30 of the second node portion 28.

As illustrated in FIG. 7, the assembly 12 and the method 200 described herein further allows efficient and inexpensive shipping and handling of the assembly 12, such as by flat-packing shipping methods. As shown, the struts 14, nodes 16, and any additional hardware or portions of the assembly 12 may be sized and oriented for high density, low volume packaging and transported for assembly without substantial labor or equipment.

Without in any way limiting the scope, interpretation, or application of the claims appearing below, it will be appreciated that the assembly 12 and/or the method 200 of the embodiments of the present disclosure provide a lightweight structural assembly 12 for a work machine to increase lifting capacity due to reduced weight of the assembly 12, increase acceleration of the work machine and its work tools, and reduce fuel and energy consumption with increased work efficiency. Further, in the case of a vehicular work machine, the assembly 12 and method 200 provides improved ride characteristics and handling of the vehicle due to reduced inertia from the assembly 12. Additionally, visibility, for example of a work area, is improved with the assembly 12 due to the ability to at least partially see through the assembly 12 of various embodiments. The various adhering, fastening, and joining arrangements for the assembly 12 and the various and diverse structural arrangements described herein allow formation of the assembly 12 according to flexible manufacturing methods and with resulting structure that may be tailored to a particular larger structure, application, environment, and/or requirement. Further, utilizing the adhesive 46 to join the various portions of the assembly 12, rather than welding and other methods, simplifies tooling to form the assembly 12 and avoids distortion or other undesirable results of the structure such that holes and/or other features of the assembly 12 may be machined or otherwise included before joining portions to form the assembly 12.

As used herein, “e.g.” is utilized to non-exhaustively list examples, and carries the same meaning as alternative illustrative phrases such as “including,” “including, but not limited to,” and “including without limitation.” As used herein, unless otherwise limited or modified, lists with elements that are separated by conjunctive terms (e.g., “and”) and that are also preceded by the phrase “one or more of,” “at least one of,” “at least,” or a like phrase, indicate configurations or arrangements that potentially include individual elements of the list, or any combination thereof. For example, “at least one of A, B, and C” and “one or more of A, B, and C” each indicate the possibility of only A, only B, only C, or any combination of two or more of A, B, and C (A and B; A and C; B and C; or A, B, and C). As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Further, “comprises,” “includes,” and like phrases are intended to specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.

While the present disclosure has been illustrated and described in detail in the drawings and foregoing description, such illustration and description is not restrictive in character, it being understood that illustrative embodiment(s) have been shown and described and that all changes and modifications that come within the spirit of the present disclosure are desired to be protected. Alternative embodiments of the present disclosure may not include all of the features described yet still benefit from at least some of the advantages of such features. Those of ordinary skill in the art may devise their own implementations that incorporate one or more of the features of the present disclosure and fall within the spirit and scope of the appended claims.
